Hi All,
I am wanting to install the Avstar AVX-5VA1 throttle body/injector servo on the IO-360M1B I purchased from Vans, and had acouple of questions regarding the install process and documentation.
First, the RV-7 firewall Forward instructions say nothing about the throttle body installation that I can find, and secondly the drawing OP-22 that shows the throttle and mixture attachments seem to indicate that the outlet should be on top and not the bottom, and that the throttle and mixture arm clocking is incorrect.
If someone is able to point me in the direction of some more comprehensive installation documentation I would greatly appreciate it.
If there isn't any such documentation, then I gather I should install the gasket dry and torque 5/16" nuts to 204-228 in lb (with new star lock washers) and simply re clock the mixture and throttle arms so that the suit the position of the cable locations provided in the firewall forward package?
Cheers.
Tom.

Tom,
I have a recent Van's YIO-360-M1B installed on my 7. I believe I had to just simply loosen the throttle and mixture arms and reindex as necessary to fit the throttle and mixture brackets provided in the FWF kit. No big deal. You will also find you will likley need to do the same with the governor.
BTW I got my Airworthiness issued today. Hope for 1st flight tomorrow.

Tom, did this work out for you? I'm in the same boat. I assume the servo can be installed in any orientation? (fuel input to right and output down viewing aft)?

Any particular issue with the reclocking? Where did you hold when torquing the nuts?

Dave,
I installed mine with the fuel inlet on the left side, fuel line out to spider on right side. This was the only logical installation and matched the supplied fuel lines that came with the engine. Needed to reclock mixture and throttle arms. All of this mated up nicely to Vans throttle and mixture control brackets per drawings.

Mine is fuel input on the left (facing forward) and output clocked to the right, so I think we are similar. Also matched lines from Lycoming.

My fuel output fitting was installed on the bottom, but not sure if it will clear the cowl yet. I may be better off moving the output to the top as most others seem to have installed on the top. The bottom would be easier to work on though.

It is not labelled, but I believe

is the 'alternate output' port.

The Avstar seems to match the Silverhawk EX-5VA1 quite closely. Perhaps a re-label? Anyway the doc for the Silverhawk shows the above as the alternate. It is however not labelled on the Avstar.

I wonder if anyone can confirm that the port above is the alternate out for the Avstar AVX-5VA1?

My outlet is on the bottom per the standard concept, then I bring a flex line up to my FT60 which sits on top of the injector, attached to the sump using adel clamps. I just had to re-clock those arms. When I did the nuts up I think I just held the arms with an adjustable wrench. I'll grab some photos tonight and post them for you so you can see how I routed things.
